Gordon Cowden, 51, a father who was the oldest person killed, was memorialized at Pathways Church in Denver.

Colorado Gov. John Hickenlooper, Aurora Mayor Steve Hogan and Aurora Police Chief Dan Oates were among the mourners who walked by a large portrait of Cowden at the entrance to the private service.

Cowden, a Texas native who lives in Aurora, had taken his two teenage children to the new Batman movie, "The Dark Knight Rises," early Friday midnight showing. The businessman's children escaped unharmed.

Cowden was one of 12 killed and 58 injured when a gunman wearing body armor, a gas mask and toting three firearms, opened fire at the crowded screening. James Eagan Holmes, 24, was arrested behind the theater shortly after the massacre.
